MEDALITE CONTRAINDICATIONS & PRECAUTIONS

Last updated: September 2025

The Medalite LED Mask is a wellness tool for meditation and relaxation. Because flashing/flickering lights can affect the nervous system, please review the following before use.

Quick Self‑Screening (Do not use if any apply)

• Under 18 years old

• Pregnant or breastfeeding

• Epilepsy or history of seizures, fainting, blackouts, or unexplained loss of consciousness

• History of major brain injury, brain surgery, brain tumor, or stroke

• Severe psychiatric illness (e.g., psychosis or suicidal thoughts)

• Currently intoxicated or in alcohol/drug withdrawal

• Severely sleep‑deprived (less than ~6 hours of rest)

  
  

If you are unsure, do not use Medalite until you have spoken with a qualified healthcare provider.

Absolute Contraindications — Do Not Use

• Epilepsy or any seizure disorder (including photosensitive epilepsy); family history of photosensitive epilepsy

• History of seizures, blackouts, or fainting

• Major brain injuries or conditions (e.g., traumatic brain injury, prior brain surgery, brain tumors, stroke)

• Severe psychiatric illness (e.g., schizophrenia/psychosis, active suicidal ideation)

• Under 18 years of age

• Pregnancy or breastfeeding

Relative Contraindications — Use With Caution

• Chronic migraines (especially light‑triggered)

• Severe anxiety disorders (panic disorder, PTSD, dissociation)

• Neurodegenerative diseases (e.g., Multiple Sclerosis, Parkinson’s, Alzheimer’s)

• Sleep deprivation (<6 hours), circadian disruption, or jet lag

• Acute illness or metabolic imbalance (e.g., high fever, low sodium, uncontrolled diabetes, active infection)

• Alcohol or drug use/intoxication (including withdrawal states)

  
  

If any of the above apply, consult a clinician before use. Consider shorter, lower‑intensity sessions and stop immediately if you feel unwell.

Physiological & Situational Risk Factors

• Sleep deprivation or significant fatigue

• Alcohol or drug intoxication; withdrawal from alcohol, benzodiazepines, opioids, or stimulants

• Acute illness, fever, or electrolyte/metabolic abnormalities

Special Situations

• Immediately after ketamine therapy: Use only under provider supervision; heightened sensitivity is common.

• Psychedelics or altered states (e.g., psilocybin, LSD, MDMA): Safety of combining with flashing light stimulation has not been established. Avoid unless under direct supervision of a qualified provider.

• Migraine sufferers: Consider lower intensity and shorter duration; discuss with a neurologist if needed.

Medication & Substance Considerations

Certain medicines and substances can lower the seizure threshold or increase sensitivity to light/flicker. Discuss with your doctor before use if you take any of the following:

Antidepressants
• Higher risk: bupropion (Wellbutrin), tricyclics (e.g., clomipramine)
• Most SSRIs/SNRIs: generally low risk at prescribed doses

Antipsychotics
• Highest risk: clozapine (Clozaril)
• Moderate: olanzapine, quetiapine, risperidone
• Lower: aripiprazole (Abilify)

Stimulants
• ADHD medications (methylphenidate, amphetamines): generally safe as prescribed; risk rises with overdose or severe sleep loss

Opioids / Analgesics
• tramadol, tapentadol, meperidine — may provoke seizures

Antibiotics
• Higher risk: fluoroquinolones (ciprofloxacin, levofloxacin), high‑dose penicillins, carbapenems, cefepime, metronidazole, isoniazid

Other drugs & supplements
• theophylline; antimalarials
• high‑dose first‑generation antihistamines
• herbal stimulants (e.g., Ginkgo biloba, St. John’s Wort, high‑dose ginseng)
• excessive caffeine intake

Risk depends on dose, individual factors, and combinations. This list is not exhaustive.
